The Delisle and Réaumur scales are both historical temperature scales. While less common today, understanding their conversions can be crucial for historical research or scientific data analysis. This blog post will guide you through the Delisle to Réaumur conversion process and provide a handy online calculator.
The Delisle scale, invented by French astronomer Joseph-Nicolas Delisle in 1732, is a descending scale. This means the boiling point of water is 0D, and the freezing point of water is 150°D.
The Réaumur scale, developed by French scientist René Antoine Ferchault de Réaumur in 1730, is also a descending scale. On this scale, the freezing point of water is 0°R, and the boiling point of water is 80°R.
The formula to convert Delisle to Réaumur is:
**Réaumur (°R) = (150 - Delisle (°D)) * (4/15)**
Simply enter the temperature in Delisle degrees (°D) into the calculator, and it will instantly display the equivalent temperature in Réaumur degrees (°R).
Let's say you have a temperature of 75°D. To convert this to Réaumur:
